Watch Alina Alt explain compute API interoperability with OpenGL (using CUDA and OpenCL APIs) and delve into interoperability at a system level (or review the slides). Alina explains challenges and benefits of dedicating one GPU for compute and another for graphics, how different system configurations affect data transfer between two GPUs, and how it translates into application design decisions helping to enable an efficient, cross-GPU interoperability between compute and graphics contexts.

Acceleware's customized 4-day OpenCL training consists of classroom lectures and several practical hands-on exercises. It is specifically tailored for learning parallel programming in OpenCL on AMD GPUs and APUs. Attendees should have a background C/C++ (2 or more years).

The Intel® SDK for OpenCL Applications 2012 provides a comprehensive development environment and tools for the build, debug, and tune stages of an OpenCL application. Join this webinar on Wednesday July 25th at 9am pacific time.

If used correctly, OpenCL images / textures can give you large speedups on GPUs. In this post, author Erik Smistad shows you a very short example of how to use OpenCL to blur/smooth an image. The goal is to show how images/textures are used in OpenCL and the benefits of using them.

Jon Peddie Research will be hosting an informational luncheon for press and analysts at SIGGRAPH 2012. The topic will be "Doing More with Multicore," and we'll have a distinguished panel to debate the different aspects of putting multiple CPU and GPU cores to work. What technology is best suited for what jobs? Or maybe a core is just a core, is just a core. The event will be held August 8, 2012 at 11:45 to 14:00 in the JW Marriott, L.A. Live - 900 W Olympic Blvd, in room PLAZA 1

Khronos member Kishonti has updated their CLBenchmark desktop edition software. CLBenchmark 1.1 Desktop Edition is an easy-to-use tool for comparing the computational performance of different platforms.

Heat transfer and, more generally, parabolic partial differential equations are a very important class of problems in physics and mathematics. Analytic solutions aren't available for real-world problems where initial and boundary conditions can be arbitrary. CMSoft presents video tutorials and source code with detailed information about how to create the CLGL shared context, use OpenCL to accelerate the simulation of heat transfer and share an OpenGL texture to present the results to the user.

At Google I/O ZiiLABS, in co-operation with Symphony Teleca, demonstrated how OpenCL can be used to deliver significant compute acceleration on Android platforms. The tablet demonstration of a new camera application, built by Symphony Teleca, uses OpenCL to implement a number of key image processing effects, comparing the performance of the algorithms implemented in both 'C' and OpenCL. The OpenCL code exploits the performance and flexibility of the underlying ZMS-40's media processing array to deliver significant advantages over CPU-only code.
